MILKING-MAGHINE To all whom it may concern:

Be it known that I, REUBEN 1 Born, a citizen of the United States, residing at Gettysburg, in the county of Adams and State of Pennsylvania, have invented a new and useful Milking-Machine, of which the following is a specification.

This invention has reference to improve ments in milking machines and is designed more particularly to provide a hand machine whereby the operation of milkin may be performed without the necessity ot grasping the teats of the cow directly in the hand.

In accordance with the present invention there is provided a cup or rercptacle of such size as to readily receive a teat and provision is made for varying the effective capacity of the cup to accommodate teats of ditlerent sizes. W'ithin the cup there provided a pressure member controllable from the ex terior of the cup by the hand of the operator so to a. ply a progressive pressure from the root 0 the teat toward the tip thereof to cause the expulsion of is so shaped as to receive a portion of the udder when the milk therein is nearly exhausted, so that the device is adapted to milk the cow dry.

he invention will be best understood from a consideration of the following detail description taken in connection with the aceompanying drawings forming a part of this specification. in which drawings Figure 1 is an elevation of the device. Fig. 2 is a central section through the body thereof, with parts in elevation. Fig. 3 is a section on the line --ll of Fig. 2.

Referring to the d rawings there shown a tent cup or receptacle l conforming .in general shape to the shape of a teat and large enough to receive the largest teat. ()ne end of this cup is open and is cut a\\'a on two sides to form recesses J, the purpose of which will appear lu-rt-inal'h-r. The other end of the cup is contracted into a neck 8, shaped to receive a conduit 4 de signed to load into a milk receiving bucket or other receptacle.

The body portion of the cup 1 may be grooved on one side as indicated at 5 to contorm to the shape of the fingers of the hand and on the other side the cup is rovided with a handle 6 through the centra portion of which there extends a tubular member 7 which may be either formed in one piece Specification of Letters Patent. Applie tion filed September 14, 1909.

the milk, and the cup Serial No. 517,737.

with the handle and body of the cup or may be separately formed therefrom and unite thereto. The massage through the tube 7 matches a. perloration in the body of the cup and, mounted in this tubular member and extending into the body of the cup is a rod 8 terminating outside the tubular member in a. pushimtton J, the purpose of whi h will hereinafter appear.

rr'ithin the cup there is lodged a plate 10 pivotally connected to the rod 8 as indirated at 8.

Connected at one end to the interior of the cup 1 near the discharge end thereof are leaf springs 11. the corresponding ends of these springs being passed one behind the other through a staple 12 so that While these springs are firmly held in place they may be readily removed for repair or cleaning. These springs 11. are appropriately bent or otherwise shaped and at their ends remote from ililht engaging; the staple l2 they pass behind a. pin 13,- extending throu h the rod 8 and promoting from opposite sides thereof close to the pivot connection 8 rod 3 and the plate 10. r

The tendency of the springs 11 is to main tain the plate 10 toward the corresponding side of the interior of the cup 1 but these springs will yield to a for e applied to the button end 9 of the rod 8 so that the end of the plate 10 adjacent to the handle 6 and rxtcmlina toihc wide end of the cup 1 will he moved toward the other side of the cup. The other rml oi the plate '10 reavhes to the null; end 3 ol' the cup and is there under control oi a screw rod ll extending through a threaded opening; in the cup. and exterior to the latter provided with a manipulating; head '15. while the end oi the rod t-t remote from the head l5 cogagrs in a recess it in the rorrrspoinling rod oi the plate 10.

'l 'hc working tacos ol' the interior of the rap l and ot the plate it] are covered with some soft elastic iuatcrial such as rubber and indicated in the drawings at 17.

The cup may be made of any suitable material and may be lacquered or provided with any suitable n'otertiug coating for sanitary purposes. i

he cup l is placed about a teat and the thumb screw 14 is adjusted so that the teat Patented Jan. 11, 1,910.

between the is pressed between he plate 10 and the opone hand and either pressin the button 9 b the palm of the hand or y the thumb, tic 1113781 end of the plate 10 is forced toward the opposite side of the cup thus compressin the teat at the root end and forcing the milr from said teat toward the neck 3 from whence it will flow to the conduit 4 and to the pail or 'otherreceptacle provided for the purpose. -By alternately releasing the rod 8 and plate 10 to the action of the springs 11 and then pressing the plate toward the opposite side of the cup, the milkin may proceed as long as necessary. The m1 kin may thus proceed until the udder above t e teat be ins to collapse because of the exhaustion o the contained milk when the cup 1 may be forced up a ainst the udder which will collapse more or ess into the re cesses 2 so that the udder may be milked completely dry. The operation of milkin may be performed oil the several teats until completed.

For the purpose of cleansing or repair the late 10 may be readily removed by with rawin the pin of the pivot 8, this being the on y positive attachment of the plate within the cup, and then the rod or bar 8 may be removed by withdrawing the pin 13 therefrom and the springs 11 may be with drawn from the staple 1 2 and the thumb screw 14 may be also removed from the cup 1 thus leaving the interior thereof free for cleansing.

\Vhat is claimed is:

1. A milking machine comprising a teat receiving cu a teat engaging member wholly housed within the confines of the cup and having a normal tendency in one (llltC- tion, and a ush-piece accessible from the exterior of te on and connected to the teat engaging-mem er near the end thereof adapted to contact with the root end of the teat.

2. A milking machine comprising a (cat cup, a handle on one side thereof, a guiding member extending through the handle, a push piece accessible from the extcriorof the cup and extending through the 'uide member to the interior of the cup ant la tent engaging member within the cup secured to the push-piece and the end of the teat enga in 1 member adapted to engage the root en 0 the teat.

3. A milking machine comprising a teat cup, a teat engaging plate therein," means accessible from tie exterior of the cup for operating the said plate, and an adjustable thumb member for the end of the plate adjacent to the dischar e and of the teat cup.

4. A milking madliine comprising a teat receiving cup, a teat engaging plate therein, means for constraining the plate to a posi tion away from a teat Within the cup, means accessible from the exterior of the cup for moving the plate toward the teat, and an adjustable sto for the end of the plate adjacent to the di charge end of the cup.

5. A milking machine comprising a teat cup having the udder end recessed, a handle on the exterior of the cup, a push-piece extending through the handle, an elastically constrained plate within the cup connected at its udder end to the push-piece and an adjustable stop for the end of the plate ad jacent to the dischar 0 end of the cup.

In testimony that. claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
